Title: Integrated circuit and method of driving same
Inventor: HAINRITSUHI KURAARU
IPC: H03F3/72
Filed: 1981-04-30
Abstract: An integrator with a sampling stage at the input side has a first capacitor with associated electronic switches and has one or more amplifier stages each having a feedback path containing a second capacitor which is connected to the output of the sampling stage. The integrator has a first polarity commutator interconnected between the output of the sampling stage and the input of the first amplifier stage and a second polarity commutator at the output of one of the amplifier stages, the second polarity commutator being operated synchronously with the first polarity commutator. By periodic actuation of the polarity commutators, the low frequency noise voltage components, having amplitudes which vary minimally within a polarity reversal period, cancel when the integration results of successive periods of opposite polarity are added and are thus substantially eliminated.

Title: Data-processing system
Inventor: NAKAGAWA MASAKI
IPC: G11B20/18
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To reduce a capacity of a memory for processing of data, by carrying out inputting of data read out from a disk, correcting of errors and outputting to buffers in predetermined counts of bytes. SOLUTION: Modulation data read out from a disk are input after demodulated to an input buffer 45 which temporarily stores the data every 8 bytes. When the 8-byte data are stored in the buffer 45, the data are transferred to a memory 48 under the control of a memory controller 51. When receiving an ECC process command from an ECC controller 50, an ECC 49 reads out every predetermined bytes, the data in an ECC block stored in the memory 48, executes an ECC process to the data and writes error-correcting data to the memory 48. When the error correction of one ECC block is completed, the data of the ECC block are read out every 8 bytes in accordance with a requirement from an extension circuit 18, and transferred to an output buffer 47.

Abstract: PURPOSE:To relieve eyestrain caused by gazing a picture on a cathode ray tube for a long time by regulating the reflectance of the cathode ray tube to <=1% for visible rays having optional wavelength and to reduce the production cost of the cathode ray tube by forming an org. thin film satisfying specified conditions on the surface of a plastic plate by a plasma polymn. process. CONSTITUTION:An org. thin film satisfying nd=lambda/4 [wherein (n) is a refractive index of the thin film; (d) is a thickness of the thin film; lambda is a wavelength of incident light into a plastic plate] is formed by a plasma polymn. process on at least a part of the plastic plate. Said plasma polymn. is restricted to that carried out at low temp. by which plasma is generated using a polymerizable gas such as a fluorine compd. or organosilicon compd. alone or as a mixture with a nonpolymerizable gas, and a thin film is formed on the surface to be treated. A reflectance of the plastic plate is reduced to <=1% for an optional wavelength of visible rays within a range 400-700nm by said thin film, and eyestrain is relieved.

Title: Method and apparatus for eliminating inter-code interference by decision feedback
Inventor: SUGIYAMA AKIHIKO
IPC: H04L25/03
Filed: 1988-03-18
Abstract: PURPOSE:To simplify the constitution and to reduce the hardware scale by taking the sum or difference between the present value and a value by several preceding data, revising the coefficient while selecting the sum or difference signal corresponding to the sampling phase thereby controlling the adaptive filter. CONSTITUTION:A decider 3 decider a data and a mode corresponding to the received symbol waveform for each Tsec and the result is fed to a switch 9, selectors 11, 15 and an adaptive filter 25. The switch 14 selects the output of a polarity detection circuit 13 or an output of the selector 15 or the output of the switch 7 based on the sampling phase and supplies the result to the adaptive filter 25. Since the selector 11 selects the symbol waveform discriminated by a discriminator 3 and the data from the memory corresponding to the symbol waveform of opposite polarity with the symbol waveform discriminated by the discriminator 3 in such a way, the reception signal is cancelled by the adder 12 to attain the extraction of residual inter-code interference accurately. Then the output of the adder 12 to control the adaptive filter 25, since the reception signal to give disturbance to the adaptive operation of the filter 25 is cancelled, the adaptive operation of the adaptive filter 25 is guaranteed.

Filed: 1994-04-05
Abstract: PURPOSE:To restrain an incident angle dependency characteristic of a phase difference, and apply a polarizing beam splitter even to diffused light by forming a metallic thin film on the uppermost layer of multilayer films. CONSTITUTION:In a polarizing beam splitter 10, a thin film 12 composed of silicon dioxide is formed on a surface of a base material 10a as a first layer, and a thin film 13 composed of silicon is formed on the surface. Preferably, these multilayer films 12 and 13 are formed by relatively layering at least a layer having a high refractive index and a layer having a low refractive index. A metallic thin film 14 is formed on the uppermost layer of the multilayer films 12 and 13, and metal used as this metallic thin film 14 is desirable to be metal having a light absorbing characteristic, for example, like chrome or the like. After the multilayer films 12 and 13 and the metallic thin film 14 are formed on a slant face of the base material 10a, it is joined to the other base material 10b having a substantially equal refractive index. For example, a UV-curing adhesive or an epoxy type adhesive or the like can be used in this joining. Thereby, since it can be applied even to diffused light or convergent light, a collimator lens becomes unnecessary.

One end of a detection shaft 33 is connected to the movable body 31 and the other end thereof passes through a bush 32 to protrude to the outside and the leading end thereof is brought into contact with an object 28 to be measured. By this constitution, the hollow interior of the guide is blocked from the effect of the fluctuation of the open air or temp. and the adhesion of dust or contamination to the mirror surface 29 is prevented. When the object 28 displaces in the axial direction, the detection shaft 33 operates in conjunction with said object and the movable body 31 moves corresponding to displacement quantity. At this time, an interference wave form detector 22 separates the interference light obtained by the light projecting receiving system 20 into respective components to form an interference light signal which is, in turn, operationally processed to calculate the displacement direction and displacement quantity of the object 28.

Abstract: PURPOSE:To make a liquid expandable raw material difficult to leak from yarn holes by piercing yarn for a loop through an overlapped part and drawing it to the other side, projecting and forming the loops in the prescribed intervals and repeating the entanglement of leno yarn and the loop and sewing the overlapped part of the end part of a skin constitutional piece. CONSTITUTION:Sewing of a skin constitutional piece is performed by entanglement of yarn 26 for a loop arranged to one side of an overlapped part 25 and leno yarn 28 arranged to the other side. Yarn 26 for a loop present in one side of the overlapped part 25 is pierced through the overlapped part 25 at every prescribed interval and drawn out in a loop shape to the other side of the overlapped part 25. A first, second and third loops 30, 30, 30,... consisting of the prescribed interval are projected and formed in the other side. The yarn holes 32, 32, 32,... are formed by piercing yarn 26 for the loop through the overlapped part 25. Leno yarn 28 present in the other side of the overlapped part 25 is entangled to the loops 30, 30,... in the other side without being drawn into the yarn holes 32. These yarn holes are made small and closed by the chainlike entanglement of yarn for the loop and leno yarn. A liquid expandable raw material is prevented from being leaked through the yarn holes at a time for expansion molding integrated to skin.
